Design
Figure 4-21 DP/RS232C Link for PROFIBUS DP
The DP/RS232C Link (6ES7 158-0AA01-0XA0) consists of a compact 70 mm housing for
DIN rail mounting. Ideally the module should be installed vertically. The modules can be
inserted one beside the other without gaps being necessary. The system is connected to
PROFIBUS DP via a 9-pin D-sub socket. The RS232C interface is implemented as a 9pin D-
sub connector.
Area of application
The PROFIBUS DP/RS232C Link is a converter between an RS232C (V.24) interface and
PROFIBUS DP. Devices with an RS232C interface can be linked to PROFIBUSDP with the
DP/RS232C Link. The DP/RS232C Link supports the procedures 3964 R and free ASCII
protocol.
